Sirui Aurora 85mm f/1.4 is an autofocus prime lens designed for full-frame mirrorless cameras, available for Sony E, Nikon Z, Leica L, and Fujifilm X mounts. The 85 mm focal length and f/1.4 maximum aperture make it suitable for portraiture, detail photography, events, available-light shooting, and video work with shallow depth of field. The optical design consists of 14 elements in 9 groups and includes aspherical, ED, and high-refractive-index elements, intended to help control chromatic aberration, distortion, and contrast loss. The 15-blade diaphragm contributes to a smooth out-of-focus rendering, useful in situations where subject-background separation is important. The focusing system supports autofocus and manual focus, with a minimum focusing distance of 0.85 m and a maximum magnification ratio of 0.115x. The lens uses 67 mm filters, has a minimum aperture of f/16, and covers the full-frame format, with a diagonal angle of view of approximately 28.64°. Weight varies depending on the mount, with approximately 540 g for the Sony E version and about 550 g for the Fujifilm X and Leica L versions. Sirui Aurora 85mm f/1.4 is intended for users looking for a bright short telephoto lens with autofocus, a relatively compact construction for its class, and optical features suited to portrait photography and video production.
